Abstract
A vehicle (e.g., a truck) rubber air spring is bonded to a seat of a fixturing sleeve. A bead of the air spring has a rubber primer thereon and the seat of the fixturing sleeve has a fixturing primer thereon. An adhesive located between the rubber and fixturing primers permanently secures the air spring to the sleeve seat.
Claims11
A vehicle air spring bonded to a support sleeve, comprising;
- a rubber air spring including sidewall casing plies and a bead portion;
- a fixturing sleeve having a seat, said seat designed to receive said bead portion of said rubber air spring, and an adhesive laminate located on and between said sleeve seat and said air spring bead and adhering said bead to said sleeve seat, said adhesive laminate comprising a rubber primer, a fixturing primer, and a cured adhesive, said rubber primer being a halogen donating compound, or a trichlorotriazinetrione, or a N-halohydantoin, or a N-haloamide, or a N-haloimide, or an acetamide, or combinations thereof.
An adhesive laminate for adhering a rubber to a metal, comprising;
- a reacted rubber primer layer, a metal primer layer, and a cured adhesive layer located between said rubber primer layer and said metal primer layer, wherein said rubber primer is a halogen donating compound, or a trichlorotriazinetrione, or a N-halohydantoin, or a N-haloamide, or a N-haloimide, or an acetamide, or combinations thereof;
- wherein said metal primer is a mixture comprising a chlorosulfonated polyethylene, a chlorinated paraffin, and a polydinitrosobenzene;
- or an aqueous composition comprising a polyvinyl alcohol stabilized aqueous phenolic resin dispersion;
- and wherein said adhesive is an epoxy based resin, or a polyurethane adhesive, or a polymer containing an acid halide group or a haloformate group, or a polymer containing an anhydride group which upon reaction with a diamine yields an amine-acid linkage.
